Dear student

As per my knowledge you can't do.From 2018 on-wards, only science (PCM or PCMB) students who have scored atleast 50% in class 12th with mathematics as compulsory subject will be considered eligible to appear in architecture entrance exams.

Before 2018, commerce with maths students who did secure atleast 50% in class 12th were eligible to appear in architecture entrance exams.
